After Zhou Tian manifested his cultivation level, he could indeed make those deities retreat in the shortest possible time. However, if Zhou Tian did not display his true cultivation level, given the situation at the time, Zhou Tian had a feeling that unless unexpectedly, those deities would likely not easily retreat without suffering significant casualties.
In such a situation, Zhou Tian could ensure his own safety while facing such a large group of opponents. If Zhou Tian truly intended, he could indeed engage in a fight with that group of deities.
If he were to just rely on his own diligent cultivation, his cultivation level might increase, but such growth does not necessarily equate to a corresponding increase in strength. Given Zhou Tian's circumstances, if various incidents had not continually occurred, he would have long had the idea of practicing the time rule.
